1. FIELD

Provided herein are pharmaceutical compositions comprising (S)-2-(2,6-dioxopiperidin-3-yl)-4-((2-fluoro-4-((3-morpholinoazetidin-1-yl)methyl)benzyl)amino)isoindoline-1,3-dione, or an enantiomer, mixture of enantiomers, tautomer, isotopolog, or pharmaceutically acceptable salt thereof, and a carrier or diluent.

2. BACKGROUND

Cancer is characterized primarily by an increase in the number of abnormal cells derived from a given normal tissue, invasion of adjacent tissues by these abnormal cells, or lymphatic or blood-borne spread of malignant cells to regional lymph nodes and metastasis. Clinical data and molecular biologic studies indicate that cancer is a multistep process that begins with minor preneoplastic changes, which may under certain conditions progress to neoplasia. The neoplastic lesion may evolve clonally and develop an increasing capacity for invasion, growth, metastasis, and heterogeneity, especially under conditions in which the neoplastic cells escape the host’s immune surveillance. Current cancer therapy may involve surgery, chemotherapy, hormonal therapy and/or radiation treatment to eradicate neoplastic cells in a patient. Recent advances in cancer therapeutics are discussed by Rajkumar et al. in Nature Reviews Clinical Oncology 11, 628-630 (2014).

All of the current cancer therapy approaches pose significant drawbacks for the patient. Surgery, for example, may be contraindicated due to the health of a patient or may be unacceptable to the patient. Additionally, surgery may not completely remove neoplastic tissue. Radiation therapy is only effective when the neoplastic tissue exhibits a higher sensitivity to radiation than normal tissue. Radiation therapy can also often elicit serious side effects. Hormonal therapy is rarely given as a single agent. Although hormonal therapy can be effective, it is often used to prevent or delay recurrence of cancer after other treatments have removed the majority of cancer cells.

Despite availability of a variety of chemotherapeutic agents, chemotherapy has many drawbacks. Almost all chemotherapeutic agents are toxic, and chemotherapy causes significant, and often dangerous side effects including severe nausea, bone marrow depression, and immunosuppression. Additionally, even with administration of combinations of chemotherapeutic agents, many tumor cells are resistant or develop resistance to the chemotherapeutic agents. In fact, those cells resistant to the particular chemotherapeutic agents used in the treatment protocol often prove to be resistant to other drugs, even if those agents act by different mechanism from those of the drugs used in the specific treatment. This phenomenon is referred to as pleiotropic drug or multidrug resistance. Because of the drug resistance, many cancers prove or become refractory to standard chemotherapeutic treatment protocols.

Hematological malignancies are cancers that begin in blood-forming tissue, such as the bone marrow, or in the cells of the immune system. Examples of hematological malignancies are leukemia, lymphoma, and myeloma. More specific examples of hematological malignancies include but are not limited to acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), multiple myeloma (MM), non-Hodgkin’s lymphoma (NHL), diffuse large B-cell lymphoma (DLBCL), Hodgkin’s lymphoma (HL), T-cell lymphoma (TCL), Burkitt lymphoma (BL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), marginal zone lymphoma (MZL), and myelodysplastic syndromes (MDS).

The variety of possible pharmaceutical compositions (e.g., oral dosage formulations comprising different excipients) creates potential diversity in physical and chemical properties for a given pharmaceutical compound. The discovery and selection of pharmaceutical compositions are of great importance in the development of an effective, stable and marketable pharmaceutical product.

5. DETAILED DESCRIPTION 5.1 Definitions

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications are incorporated by reference in their entirety. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

As used herein, and in the specification and the accompanying claims, the indefinite articles “a” and “an” and the definite article “the” include plural as well as single referents, unless the context clearly indicates otherwise.

As used herein, the terms “comprising” and “including” can be used interchangeably. The terms “comprising” and “including” are to be interpreted as specifying the presence of the stated features or components as referred to, but does not preclude the presence or addition of one or more features, or components, or groups thereof. Additionally, the terms “comprising” and “including” are intended to include examples encompassed by the term “consisting of”. Consequently, the term “consisting of” can be used in place of the terms “comprising” and “including” to provide for more specific embodiments of the invention.

The term “consisting of” means that a subject-matter has at least 90%, 95%, 97%, 98% or 99% of the stated features or components of which it consists. In another embodiment the term “consisting of” excludes from the scope of any succeeding recitation any other features or components, excepting those that are not essential to the technical effect to be achieved.

Typically, the compositions are formulated for single dosage administration. To formulate a composition, the weight fraction of compound is dissolved, suspended, dispersed or otherwise mixed in a selected vehicle at an effective concentration such that the treated condition is relieved or ameliorated. Pharmaceutical carriers or vehicles suitable for administration of the compounds provided herein include any such carriers known to those skilled in the art to be suitable for the particular mode of administration.

In addition, the compounds may be formulated as the sole pharmaceutically active ingredient in the composition or may be combined with other active ingredients. Liposomal suspensions, including tissue-targeted liposomes, such as tumor-targeted liposomes, may also be suitable as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art. For example, liposome formulations may be prepared as known in the art. Briefly, liposomes such as multilamellar vesicles (MLV’s) may be formed by drying down egg phosphatidyl choline and brain phosphatidyl serine (7:3 molar ratio) on the inside of a flask. A solution of a compound provided herein in phosphate buffered saline lacking divalent cations (PBS) is added and the flask shaken until the lipid film is dispersed. The resulting vesicles are washed to remove unencapsulated compound, pelleted by centrifugation, and then resuspended in PBS.

The active compound is included in the pharmaceutically acceptable carrier in an amount sufficient to exert a therapeutically useful effect in the absence of undesirable side effects on the patient treated. The therapeutically effective concentration may be determined empirically by testing the compounds in in vitro and in vivo systems described herein and then extrapolated therefrom for dosages for humans.

The concentration of active compound in the pharmaceutical composition will depend on absorption, tissue distribution, inactivation, metabolism and excretion rates of the active compound, the physicochemical characteristics of the compound, the dosage schedule, and amount administered as well as other factors known to those of skill in the art.

Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include any of the following components: a sterile diluent, such as water for injection, saline solution, fixed oil, polyethylene glycol, glycerine, propylene glycol, dimethyl acetamide or other synthetic solvent; antimicrobial agents, such as benzyl alcohol and methyl parabens; antioxidants, such as ascorbic acid and sodium bisulfite; chelating agents, such as ethylenediaminetetraacetic acid (EDTA); buffers, such as acetates, citrates and phosphates; and agents for the adjustment of tonicity such as sodium chloride or dextrose. Parenteral preparations can be enclosed in ampules, pens, disposable syringes or single or multiple dose vials made of glass, plastic or other suitable material.

In instances in which the compounds exhibit insufficient solubility, methods for solubilizing compounds may be used. Such methods are known to those of skill in this art, and include, but are not limited to, using cosolvents, such as dimethylsulfoxide (DMSO), using surfactants, such as TWEEN®, or dissolution in aqueous sodium bicarbonate.

Upon mixing or addition of the compound(s), the resulting mixture may be a solution, suspension, emulsion or the like. The form of the resulting mixture depends upon a number of factors, including the intended mode of administration and the solubility of the compound in the selected carrier or vehicle. The effective concentration is sufficient for ameliorating the symptoms of the disease, disorder or condition treated and may be empirically determined.

The pharmaceutical compositions are provided for administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, granules, sterile parenteral solutions or suspensions, and oral solutions or suspensions, and oil water emulsions containing suitable quantities of the compounds or pharmaceutically acceptable salts thereof. The pharmaceutically therapeutically active compounds and salts thereof are formulated and administered in unit dosage forms or multiple dosage forms. Unit dose forms as used herein refer to physically discrete units suitable for human and animal subjects and packaged individually as is known in the art. Each unit dose contains a predetermined quantity of the therapeutically active compound sufficient to produce the desired therapeutic effect, in association with the required pharmaceutical carrier, vehicle or diluent. Examples of unit dose forms include ampules and syringes and individually packaged tablets or capsules. Unit dose forms may be administered in fractions or multiples thereof. A multiple dose form is a plurality of identical unit dosage forms packaged in a single container to be administered in segregated unit dose form. Examples of multiple dose forms include vials, bottles of tablets or capsules or bottles of pints or gallons. Hence, multiple dose form is a multiple of unit doses which are not segregated in packaging.

Dosage forms or compositions containing active ingredient in the range of 0.005% to 100% with the balance made up from non toxic carrier may be prepared. For oral administration, a pharmaceutically acceptable non toxic composition is formed by the incorporation of any of the normally employed excipients, such as, for example pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose derivatives, sodium crosscarmellose, glucose, sucrose, magnesium carbonate or sodium saccharin. Such compositions include solutions, suspensions, tablets, capsules, powders and sustained release formulations, such as, but not limited to, implants and microencapsulated delivery systems, and biodegradable, biocompatible polymers, such as collagen, ethylene vinyl acetate, polyanhydrides, polyglycolic acid, polyorthoesters, polylactic acid and others. Methods for preparation of these compositions are known to those skilled in the art.

The active compounds or pharmaceutically acceptable salts may be prepared with carriers that protect the compound against rapid elimination from the body, such as time release formulations or coatings.

The compositions may include other active compounds to obtain desired combinations of properties. The compounds provided herein, or pharmaceutically acceptable salts thereof as described herein, may also be advantageously administered for therapeutic or prophylactic purposes together with another pharmacological agent known in the general art to be of value in treating one or more of the diseases or medical conditions referred to hereinabove, such as diseases related to oxidative stress. It is to be understood that such combination therapy constitutes a further aspect of the compositions and methods of treatment provided herein.

(F) Process for Making Dosage Forms

Pharmaceutical compositions (dosage forms) provided herein can be prepared by any of the methods of pharmacy, but all methods include the step of bringing the active ingredient into association with the excipient, which constitutes one or more necessary ingredients.

6.2 Cell-Based Assays Using Compound 1

The following are examples of cell-based assays that can be used to determine the anti-proliferative activity and apoptotic effect of Compound 1 using exemplary non-Hodgkin lymphoma (NHL) cell lines.

Cell Proliferation and Viability Assay Using SU-DHL-4 Cell Line: The following exemplary assay uses a DLBCL cell line, for example, the SU-DHL-4 cell line (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH [DSMZ]: catalogue number ACC-495) at 120 hours post-treatment. The seeding density for SU-DHL-4 can be optimized to ensure assay linearity in 1536-well plates.

Increasing concentrations (0.5 nM to 10 µM) of Compound 1 were each spotted in a 20-point dilution fashion (unevenly spaced data points) via an acoustic dispenser (EDC ATS-100) into an empty 1536-well plate. The DMSO concentration was kept constant for a final assay concentration of 0.1% DMSO. Prior to testing, SU-DHL-4 cells were grown in RPMI-1640 (Roswell Park Memorial Institute - 1640) medium with 10% FBS (fetal bovine serum: HyClone) and expanded in culture flasks to provide sufficient amounts of starting material. Cells were then diluted to 500 cells per well in a 5 µL volume, and added directly to the compound-spotted 1536-well plates. Cells were allowed to grow for 120 hours in 5% CO₂ at 37° C. At the time when exposure of cells to compound began (t₀), initial viable cell number was assessed via Cell Titer-Glo® Luminescent Cell Viability Assay at a 1 vol: 2 vol ratio according to manufacturer’s instructions (Promega Corporation, Madison, WI) by quantifying the level of luminescence generated by adenosine-5′-triphosphate (ATP) present in viable cells. After 120 hours, cell viability of the treated cells was assessed via Cell Titer-Glo® and read for luminescence. All growth inhibition curves were processed and evaluated using Activity Base (IDBS, Alameda, CA). Cell viability IC₅₀ values were calculated using a four parameter logistic model (sigmoidal dose-response model):

$\text{y} = {\left( {\text{A+}\left( \left( \text{B-A} \right) \right)} \right)/\left( {1 + \left( {\left( \text{C} \right)/\left( \left( \left( \left( {\left. \left( \text{x} \right) \right.\hat{}\text{D}} \right) \right) \right) \right)} \right)} \right)}$

wherein:

-   A = Y_(Min) -   B = Y_(Max) -   C = EC₅₀ -   D = Hill slope -   IC₅₀ = the concentration of the compound when Y = 50% of DMSO     control -   Y = cell viability measured as luminescence unit, and -   x = concentration of compound.

Compound 1 was found to have activity in SU-DHL-4 cell proliferation assay with an IC₅₀ < 0.2 µM.

Cell Proliferation and Viability Assay Using Hematological Cell Lines: The following exemplary anti-proliferative assay uses exemplary hematological cell lines in the following. The in vitro growth inhibitory activity of Compound 1 described herein was evaluated using a 384-well flow cytometry assay.

The cell lines were plated in 384-well flat bottom plates and assessed with increasing concentrations of compound ranging from 0.00015 to 10 µM or dimethyl sulfoxide (DMSO) control. The final concentration of DMSO was 0.1% (v/v). Following the addition of Compound 1 or DMSO and incubation for 120 hours, cell number and cell death were analyzed by flow cytometry (Attune®, Thermo Fisher) using Annexin V and the live-cell impermeant DNA dye, DRAQ7. Phosphatidylserine translocates from the inner layer to the outer layer of the cell membrane early in apoptosis and Annexin V binds to the exposed phosphatidylserine found on the surface of an apoptotic cell. The vital dye DRAQ7 is excluded by intact live cells and only stains cells that have died as a result of apoptosis or necrosis.

Flow cytometry data analysis was then performed using the Flow Jo_v10 software to determine the number of viable cells (Annexin V and DRAQ7 double negative staining cells) and percentage of apoptotic cells (Annexin V positive cells) for each condition. The live cell count for every concentration was normalized to the DMSO control (considered as 100%) to calculate the percentage of viable cells remaining after treatment and graphed using GraphPad Prism 7.03. The IC₅₀ (50% inhibitory concentration) and E_(max) (maximum efficacy achieved) values were then calculated by performing nonlinear regression curve fitting using log(inhibitor) vs. normalized response - variable slope analysis on GraphPad Prism 7.03. Area under the curve (AUC) was calculated by performing area under curve analysis on GraphPad Prism 7.03. Similarly, for apoptosis analysis, the percentage of apoptosis combining both “early” (Annexin V positive and DRAQ7 negative) and “late” apoptosis (Annexin V and DRAQ7 positive) cell gates relative to DMSO was graphed using GraphPad Prism 7.03. The AUC, EC₅₀ (concentration of compound that produces half-maximal apoptosis response) and Y_(max) (maximal percentage of apoptosis achieved) values from apoptosis curves were calculated by performing area under curve analysis and nonlinear regression curve fitting using log(agonist) vs. normalized response - Variable slope analysis on GraphPad Prism 7.03.

Dose-response proliferation curves for the panel of hematological cell lines and non-linear curve-fit regression were used to determine IC₅₀, AUC, and E_(max) for% viable cells (E_(max) for viability varies between 100 at low doses and 0 at high doses, which corresponds to inhibition of all viable cells), and dose-response apoptosis curves were used to determine the EC₅₀, AUC, and Y_(max) for% apoptosis (Y_(max) for apoptosis varies from 0 at low doses and 100 at higher doses which corresponds to death of all cells). Tumor cells were exposed to serial dilutions (0.00015 to 10 µM) of Compound 1 or dimethyl sulfoxide (DMSO) control for 5 days. Viability and apoptosis for all cell lines was determined by Annexin V/7-aminoactinomycin D (7-AAD) flow cytometry. Compound 1 was found to have antiproliferative activity and/or apoptotic effects in almost all hematological cell lines tested, as shown in the following table.

6.3 Excipient Compatibility Excipient Compatibility Study Design

The purpose of excipient compatibility study is to evaluate the impact of each excipient on Compound 1 stability, rank order excipient in each function category, and provide rational basis for excipient selection.

The following table listed the compositions of the excipient compatibility blends. The excipients covered many functionalities, including diluents, binders, disintegrant, glidant and lubricants. Considering the relatively high solubility of Compound 1, compared to the low dose (as low as 0.1 mg), dissolution might not be a critical issue, so surfactants were not included in the this excipient evaluation.

Due to low dose strength, segregation and content uniformity (CU) variation could be major process challenges. Granulation process (roller compaction or high shear wet granulation) might offer better options than direct blending to minimize segregation. Therefore, for each formulation blend, besides powder mix, compressed slug samples were made to mimic roller compression condition, and wet & dried samples were made to mimic wet granulation process condition.

The samples were evaluated for both chemical and chiral stability after subjecting the mixtures to open conditions at 5° C. (control), 50° C. (dry), and 50° C./75% RH (wet) for 2 weeks. Duplicate samples were prepared for each time point and condition.

Excipient Compatibility Protocol

For each blend in the table, different forms (blend mix, slug and wet & dried mix) were used to mimic direct blend, roller compaction and wet granulation process conditions.

For each formulation blend, 120 mg of Compound 1 HCl salt (Form A) and corresponding excipients were accurately weighed. The blends were prepared by mixing for 20 minutes at 32 rpm on a Turbula mixer. For the slug sample, the blend was compressed in RRDI into slugs at 4.4KN for 100 ms. For wet mix sample, 20% water was added to the blend powder, magnetic stirring for 5 min, then put in the 50° C. oven for 1 hour.

All the samples were put on stability at 5° C., 50° C. ambient, 50° C./75% RH for 2 weeks for both chemical stability and chiral stability. The following two tables showed the chemical assay and chiral assay data, respectively.

6.4 Prototype Formulation Stability Prototype Formulation Design

Prototype capsule formulations were selected based on the results of excipient compatibility study, as shown in the following table.

For direct blending and roller compaction processes, since MCC and pregelatinized starch showed similar performance in stability in excipient compatibility, both were used in prototype formulations as binders; silicon dioxide was used as glidant; magnesium stearate and sodium stearyl fumarate were used as lubricants.

For wet granulation process, both MCC and pregelatinized starch were used, though the pregelatinized starch showed slightly better performance than MCC in excipient compatibility; silicon dioxide was not used; stearic acid, not magnesium stearate or sodium stearyl fumarate, was used as lubricant.

Prototype Formulations Preparation

For direct blending formulations (Cap-1, Cap-2, Cap-3), excipients were passed through 30 mesh/595 µm screen, API was passed through 60 mesh/250 µm screen first; geometric dilution was used to improve mixing content uniformity - API was mixed with small portion of starch or MCC first at 15 rpm for 20 minutes, comil then mixed with the rest of the excipients (except magnesium stearate) at 15 rpm for 20 minutes, comil again, rinse the comil with mannitol, then final blend at 15 rpm for 10 minutes. If magnesium stearate was used as lubricant, magnesium stearate was added at the end for additional 3 minutes’ blending at 15 rpm.

For roller compaction formulations (Cap-4, Cap-5, Cap-6), excipients were passed through 30 mesh/595 µm screen, API was passed through 60 mesh/250 µm screen first; geometric dilution was used to improve mixing content uniformity - API was mixed with small portion of starch or MCC first at 15 rpm for 20 minutes, comil (457 µm screen) then mixed with the rest of the intragranular excipients (except magnesium stearate) at 15 rpm for 20 minutes, comil (457 µm screen) again, rinse the comil with mannitol, then blend at 15 rpm for 10 minutes. If magnesium stearate was used as lubricant, intragranular magnesium stearate portion was added at the end for additional 3 minutes’ blending at 15 rpm. The intragranular blend then was passed through a Gerteis Polygran roller compactor (serreated rolls, roll speed 2 rpm, roll gap 2.0 mm, roll force 4 kN/cm, screen opening 1.0 mm, granulator speed 50 rpm). Finally, extragranular lubricant was blended with the dry granules.

For wet granulation formulations (Cap-7, Cap-8, Cap-9), all excipients (except lubricant) and API were passed through 30 mesh/595 µm screen first, then were mixed in a Freund Vector high shear granulator bowl for 10 minutes at 300 rpm impeller speed and 3000 rpm chopper speed, then spray 20% water at 30 g/min with the same 300 rpm impeller speed and 3000 rpm chopper speed, followed by 1 minute of wet massing. The wet granules were passed through 5 mesh/4 mm screen, then dried in a Mini Glatt fluid bed dryer (inlet air temp 50° C., inlet air flow 50 CFM, product temp NMT 42° C.). The dried granules were passed through comil (610 µm screen), then blended with 30 mesh screened stearic acid (lubricant) for 10 minutes at 15 rpm.

All final blends were encapsulated in a Bosch GKF 702 encapsulator into Size 4 white opaque HPMC capsules with 75 mg fill weight.

The following table showed the initial testing results of the prototype formulation batches under different process conditions. For the same formulation compositions, batches using roller compaction process always had smaller AV values than batches using direct blending process (Cap-4 vs Cap-1, Cap-5 vs Cap-2, Cap-6 vs Cap-3); therefore, for better content uniformity, roller compaction process is preferred to direct blending process for Compound 1 HC1 salt drug product manufacturing. Different processes had an impact on chemical stability. Total chemical degradation did not change much after roller compaction process, compared to direct blending; however, degradation increased after wet granulation process, which implied that wet granulation process might have a higher chemical stability risk level than roller compaction process. Chiral purity was not affected by different process conditions.

Stability of Prototype Formulations

Capsules of each formulation were packaged into 50 100 CC HDPE bottles, induction sealed, 10 counts per bottle; 35 bottles with 2 g desiccants, 15 bottles without desiccants. Stability was evaluated on the accelerated conditions (40° C./75% RH and 50° C./75% RH).

FIG. 1A, FIG. 1B, and FIG. 1C show chemical stability (total impurity) of prototype formulations for up to 12 weeks at 40° C./75% RH without desiccant, at 40° C./75% RH with desiccant, and at 50° C./75% RH with desiccant, respectively.

For the effect of desiccant vs no-desiccant on stability at 40° C./75% RH, formulations packaged with desiccant showed significantly slower impurity growth rate of API than the formulations packaged without desiccant, which implied that humidity control was important for drug product stability and hydrolysis was one of the main degradation pathways for Compound 1 HCl salt. Desiccant is needed to maintain Compound 1 HCl salt drug product shelf life.

For the three roller compaction formulations, at 40° C./75% RH with desiccant, Cap-5 and Cap-6 formulations showed similar total impurity growth rates, which was slower than that of Cap-4. At 50° C./75% RH with desiccant, the total impurity growth rates were faster than those at 40° C., but the ranking orders among the formulations did not change. The main composition difference between Cap-4 and Cap-5/Cap-6 was that magnesium stearate was used as lubricant in Cap-4, while sodium stearyl fumarate (SSF) was used in Cap-5/Cap-6 as lubricant. Therefore, SSF is preferred to magnesium stearate as lubricant in RC formulation. The binder used in Cap-5 was pregelatinized starch, while in Cap-6 it was microcrystalline cellulose. Cap-5 and Cap-6 had similar chemical stability profiles.

For the three wet granulation formulations, at 40° C./75% RH with desiccant, Cap-9 had a much faster impurity growth rate than Cap-7 and Cap-8. At 50° C./75% RH with desiccant, the impurity growth rates were faster than those at 40° C., but the ranking orders among the formulations did not change; Cap-8 had slightly faster impurity growth rate than Cap-7.

Cap-5 and Cap-7 had similar formulation compositions, but went through different granulation processes. Wet granulation formulation (Cap-7) had higher initial impurity level than roller compaction formulation (Cap-5), probably due to the process; while they had similar total impurity growth rates during stability.

FIG. 2A, FIG. 2B, and FIG. 2C show chiral stability data of prototype formulations for up to 12 weeks at 40° C./75% RH without desiccant, at 40° C./75% RH with desiccant, and at 50° C./75% RH with desiccant, respectively.

For the effect of desiccant vs no-desiccant on stability at 40° C./75% RH, formulations packaged with desiccant showed significantly slower chiral isomerization rate of API than the formulations packaged without desiccant, which implied that humidity control was important for drug product chiral stability, desiccant is needed to maintain drug product shelf life.

For the roller compaction formulations, at 40° C./75% RH with desiccant, all three formulations showed slow chiral isomerization rates - about 1% decrease in chiral purity within 12 weeks. The order in chiral stability seemed to be Cap-4 > Cap-5 > Cap-6. At 50° C./75% RH with desiccant, the chiral isomerization rates were faster than those at 40° C., but the ranking orders among the formulations did not change. It seemed that chiral stability had less risk than chemical stability on drug product shelf life.

For the wet granulation formulations, at 40° C./75% RH with desiccant, three formulations also showed slow chiral isomerization rates - less than 1.5% decrease in chiral purity within 12 weeks. The order in chiral stability seemed to be Cap-8 > Cap-7 > Cap-9. At 50° C./75% RH with desiccant, the chiral isomerization rates were faster than those at 40° C., but the ranking orders among the formulations did not change.

Cap-5 and Cap-7 had similar formulation compositions, but went through different granulation processes. The two formulations started with the same chiral purity level; after 12 weeks, wet granulation formulation (Cap-7) had slightly less chiral purity level than roller compaction formulation (Cap-5). Cap-5 and Cap-7 were selected for further process development.

6.5 Process Evaluation Development (A) High-shear Wet Granulation Process Evaluation and Development Intragranular /Extragranular Excipient Ratio

The proposed clinical dose strength for Compound 1 HCl salt drug product was as low as 0.1 mg filled in 75 mg capsule, which was about 0.14% in drug load. Such an extremely low drug load presented challenges to process and content uniformity. High-shear wet granulation process not only could disperse the API well with high shear forces during blending, but could also form granules to prevent segregation during bulk storage and encapsulation. High-shear wet granulation process could be a good choice for low dose formulations with content uniformity concerns.

In order to improve the content uniformity of Cap-7 batch (CU%RSD 6.1%, AV 16.5), the wet granulation process was optimized. Since API drug amount was fixed, the intragranular/extragranular excipient ratio was reduced (from 95/5 to 23/77) to increase the intragranular blend drug load from 0.14% to 0.6%. FIG. 3 showed the process maps of wet granulation process. In the initial process, everything except for the lubricant was in the intragranular portion; while in the new process, API, pregelatinized starch and crospovidone were in the intragranular portion, mannitol and lubricant were in the extragranular portion.

Cap-10 batch was made using intragranular /extragranular excipient ratio of 23:77, while Cap-7 used intragranular /extragranular excipient ratio of 95:5. The process result of Cap-10 (CU%RSD 2.5%, AV 5.27) indicated that reducing intragranular /extragranular excipient ratio for wet granulation process could improve content uniformity. To confirm that conclusion, repeat batches were made - Cap-11 repeated the process of Cap-7, which used the initial high intragranular /extragranular excipient ratio of 95:5; while Cap-13 repeated the process of Cap-10. The process results in the following table showed that the batch repeatability was good -- CU%RSD of Cap-7 and Cap-11 were comparable (6.1 vs 6.8), but much higher than those of Cap-10 and Cap-13 (2.5 vs 3.3). Therefore, it was confirmed that the new wet granulation process of lower intragranular /extragranular excipient ratio would improve content uniformity of low dose formulations.

TABLE 13 Summary process results of high-shear wet granulation development batches Lot Number Strength API Screen Excipient screen Assay (%) CU%RSD AV Cap-7 0.1 mg 30 mesh 30 mesh 101.46 6.1 16.51 Cap-10 0.1 mg 30 mesh 30 mesh 101.7 2.5 5.27 Cap-11 0.1 mg 30 mesh 30 mesh 109.4 6.8 21.5 Cap-12 0.1 mg 60 mesh 30 mesh 99.1 3.5 8.5 Cap-13 0.1 mg 30 mesh 30 mesh 96.2 3.3 10.3 Cap-14 0.1 mg 60 mesh 30 mesh 91 2.0 11.5 API screen pore size

API particle size could also affect content uniformity, because smaller API particles could be better dispersed. Compound 1 HCl salt API crystals tend to agglomerate; although the high shear blending force could break up agglomerates, for low dose formulation, it’s not as efficient as passing through mesh screens. For high intragranular /extragranular excipient ratio process, batch Cap-12 passed API through 60 mesh (250 µm) screen, compared with Cap-7 and Cap-11 using 30 mesh (595 µm) screen. As the result, CU%RSD was greatly reduced from 6.1% of Cap-7 to 3.5% of Cap-12. The trend was also true for the new wet granulation process of lower intragranular /extragranular excipient ratio -- CU%RSD was reduced to 2.0% in Cap-14 from 2.5% of Cap-10 after changing the API screen mesh number from 30 to 60. Therefore, passing API through smaller screen pore size could improve batch content uniformity.

Milled Granule Particle Size Match

In the low intragranular /extragranular excipient ratio (23/77) wet granulation process, the API was mixed with starch, crospovidone and water, formed wet granules and then dried and milled through comil; the milled granules were then mixed with mannitol and lubricant to form the final blend. Since mannitol powder accounted for the majority (~72% w/w) of the final blend, it’s important for the particle size of the milled granules to match that of mannitol to minimize segregation.

Cap-13 was the repeat batch of Cap-10, using the lower intragranular /extragranular excipient ratio. Cap-10 had good CU data, but the CU of Cap-13 was not as good (3.3 vs 2.5). The following table listed the particle size distribution of Cap-10, Cap-13 and mannitol excipient (Pearlitol 200SD). The particle size of Cap-10 milled granules (D50 145 µm) matches the size of mannitol (D50 148 µm) well; however, the particle size of Cap-13 milled granules (D50 259 µm) was much larger than the size of mannitol (D50 148 µm), which might explain why the CU data of Cap-13 was not as good as Cap-10. The particle size of the final blends of Cap-10 and Cap-13 were similar because mannitol was the major component and dominated the average particle size of the final blend, not the milled granules.

In another repeat batch (Cap-14), the particle size of milled granules was monitored and controlled before mixing with mannitol and lubricant. The milled granule size (D50 139 µm) matched that of Cap-10 milled granules and mannitol, which might explain why the CU%RSD of Cap-14 (2.0) was as good as that of Cap-10 (2.5).

TABLE 14 Particle size distributions of wet granulation batches and main excipients Sample Name D (10) (µm) D (50) (µm) D (90) (µm) Cap-10 milled granules 38 145 448 Cap-10 final blend 73 158 323 Cap-13 milled granules 76 259 573 Cap-13 final blend 62 150 301 Cap-14 milled granules 33 139 440 Cap-14 final blend NT NT NT Mannitol (Pearlitol 200SD) 85 148 237 Pregelatinized starch (Starch 1500) 18 88 183 NT: not tested

SEM images (not shown herein) were taken from excipients, milled granules and final blends to have a better understanding on the size and surface morphology of the particles. The SEM images of pregelatinized starch (Starch 1500) and mannitol (Pearlitol 200SD) showed that most of the pregelatinized starch particles were smaller than mannitol particles. The SEM images of Cap-10 milled granules showed that the milled granule particles were mostly aggregates of starch particles, and size of the granules were similar to that of mannitol. The SEM images of Cap-10 final blend showed that it consisted of mannitol particles.

In summary, for high-shear wet granulation process, the content uniformity of low dose formulation can be improved, when reducing the intragranular /extragranular excipient ratio, passing API through smaller pore size screen and matching the size of milled granules to that of mannitol.

(B) Roller Compaction Process Evaluation and Development Intragranular /Extragranular Excipient Ratio

The proposed clinical dose strength for Compound 1 HCl salt drug product was as low as 0.1 mg filled in 75 mg capsule, which was about 0.14% in drug load. Such an extremely low drug load presented challenges to process and content uniformity. Roller compaction process itself could not help API dispersed evenly, but could help prevent segregation afterwards; in order to achieve good content uniformity, the API should be well dispersed before the roller compaction step.

Geometric dilution was utilized in Cap-5 batch to improve blending uniformity, and got acceptable content uniformity result (3.1% RSD, AV 7.4). To further improve content uniformity, increasing the intragranular drug load before roller compaction was tested. Since API drug amount was fixed, the intragranular /extragranular excipient ratio needed to be reduced (from 98/2 to 14/86) to increase the intragranular blend drug load from 0.14% to 1%. FIG. 4 showed the process maps of RC process.

While Cap-5 used the initial roller compaction process of intragranular /extragranular excipient ratio of 98:2, Cap-15 batch was made using the new roller compaction process of intragranular /extragranular excipient ratio of 14:86. Since starch alone could not be successfully roller compacted, in Cap-15, the excipient ratios within the intragranular portion was kept similar to the excipient ratios within the extragranular portion.

In Cap-5 batch, API was passed through 60 mesh (250 µm) screen before blending; however, since it was uncommon to use 60 mesh screen for scale-up batch manufacturing, 30 mesh (595 µm) screen was used in Cap-15 batch for both API and excipients. There were no other process changes between Cap-15 and Cap-5.

The following table listed the summary process results of roller compaction development batches. The CU%RSD of Cap-15 was higher than that of Cap-5 (9.0 vs 3.1). Even a repeat batch (Cap-16) with extra blending and comiling steps did not change much on the content uniformity (CU%RSD of 8.6). Unlike wet granulation process, the new approach with lower intragranular /extragranular excipient ratio (14:86) did not improve content uniformity of low dose formulations in roller compaction process.

TABLE 15 Summary process results of roller compaction development batches Lot Number Strength API Screen Excipient screen Assay (%LC) CU%RSD AV Cap-5 0.1 mg 60 mesh 30 mesh 98.29 3.1 7.42 Cap-15 0.1 mg 30 mesh 30 mesh 103.4 9.0 19.9 Cap-16 0.1 mg 30 mesh 30 mesh 95.5 8.6 20.2 Cap-17 0.1 mg 30 mesh 30 mesh 103.8 5.8 13.9 Cap-18 0.1 mg 60 mesh 30 mesh 92.4 2.9 11.9

Particle size analysis was carried out for milled granules and final blends of roller compaction batches, and the results are listed in the following table. For Cap-15 and Cap-16 batches, the D (50) values of milled granules and final blend were similar; however, there were huge differences in D (90) values between milled granules and final blend, which indicated that milled granules had too many large particles that could not be blended well with the extragranular excipients when the extragranular excipients accounted for most of the final blend. Additional work was needed to find out the proper process conditions to control the particle size of milled granules to match the particle size of extragranular excipients for the low intragranular /extragranular excipient ratio process. However, since the conventional high intragranular /extragranular excipient ratio process could already achieve acceptable CU, more work on new process was not warranted.

TABLE 16 Particle size distributions of roller compaction batches Sample Name D (10) (µm) D (50) (µm) D (90) (µm) Cap-5 final blend 8 110 595 Cap-15 milled granules 16 145 568 Cap-15 final blend 18 126 238 Cap-16 milled granules 16 154 659 Cap-16 final blend 18 131 279 Cap-17 milled granules 15 165 786 Cap-17 final blend 14 146 780 Cap-18 milled granules 31 253 864 Cap-18 final blend 17 173 832 API screen pore size

API particle size could also affect content uniformity, because smaller API particles tend be better dispersed. Compound 1 HCl salt API crystals tend to agglomerate, and the blending process was too gentle to break down large agglomerates, so passing API powder through mesh screen before blending was an effective way to break down large agglomerates.

For initial high intragranular /extragranular excipient ratio process, batch Cap-5 passed API through 60 mesh (250 µm) screen and got acceptable CU%RSD (3.1%); however, when Cap-17 increased the API screen pore size to 30 mesh (595 µm), CU%RSD increased to 5.8%. When Cap-18 reduced the API screen pore size back to 60 mesh (250 µm), the CU% RSD went back to 2.9%. Therefore, passing API through smaller screen pore size could improve roller compaction batch content uniformity.

In summary, for roller compaction process, passing API through 60 mesh, not 30 mesh, screen was important for the content uniformity of low dose formulation.

6.6 Evaluation and Manufacture of Formulations

Cap-5 and Cap-7 had similar formulation compositions, but went through different granulation processes. Wet granulation formulation (Cap-7) had 0.7% more initial total impurity level than roller compaction formulation (Cap-5), probably because the wetting and drying of wet granulation process induced more chemical degradations; while the total impurity growth rates of the two batches were similar during stability study. Both formulations required desiccant to maintain suitable shelf life. Overall, wet granulation process had higher risk than roller compaction process in chemical stability. For chiral purity, the two formulations were similar.

Manufacturability was evaluated in content uniformity and assay value. Based on the process development data, although wet granulation batches had better content uniformity (CU%RSD) than roller compaction process, the content uniformity of the roller compaction batches were still acceptable. Roller compaction had less risk for API loss (assay value) than wet granulation process, because the roller compaction process was much simpler.

Since the solubility of Compound 1 HCl salt API was relatively high, compared to the proposed dose levels, the risk on drug product dissolution was low. FIG. 5 showed the performance (dissolution profile) of the formulations of two granulation processes. Although wet granulation batch (Cap-10) had faster dissolution rate, roller compaction batch (Cap-5) still had good enough dissolution rate.

Roller compaction and Cap-5 formulation were selected for further evaluation. The following three tables listed the formulation compositions for different dose strengths. Since desiccant was required, hydroxypropylmethyl cellulose (HPMC), not gelatin, was selected as capsule shell material, because gelatin capsules would crack in the presence of desiccant during storage.

FIG. 6 showed the process map of roller compaction process for the above batches. A description of the manufacturing process for Compound 1 HCl salt capsules is provided below: (i) Compound 1 HCl salt is pre-blended with a small portion of the pregelatinized starch, then blended with the remaining intragranular excipients (pregelatinized starch, mannitol, crospovidone, silicon dioxide, sodium stearyl fumarate); (ii) the intragranular blend is passed through a roller compactor; (iii) the extragranular silicon dioxide and sodium stearyl fumarate are passed through a screen and added to the granules and blended; and (iv) the appropriate size capsule is filled to the specified weight.

Three batches of 3 kg scale (Cap-19, Cap-20, Cap-21, 0.1 mg, 0.5 mg, and 1.5 mg dose strength respectively) were manufactured and packaged. The following table listed the results of the stability batches. The capsules were packaged in 100 CC opaque high-density polyethylene (HDPE) bottles fitted with induction seal and with tamper evident child resistant polypropylene caps. Each bottle contained 21 capsules and a 2 g desiccant.
